65 New Yorker with a 413 and hi-po manifolds. The rag joint assy will touch the flange on the manifold when accelerating. Need to replace the rag joint with something having a smaller diameter. Saw a u-joint on the flaming river site that looks like it might work. Anybody ever use one of these rag joint replacements? Know how they go in? Do you have to cut one of the shafts? Thanks- Pat
